1. A method programmed in a non-transitory memory of a device comprising:
receiving a face list and a vertex list;
receiving a high resolution depth map;
implementing patch mesh subdivision to generate a new face list and a new vertex list, wherein implementing patch mesh subdivision to generate the new face list and the new vertex list includes: a vertex split implementation by removing edges, adding a vertex and drawing lines from existing vertices to the added vertex; and
implementing three dimensional reconstruction with the new face list and the new vertex list to generate a decoded mesh object.
